Precast interconnectable concrete paver block for constructing paving surface

Abstract

A culvert structure interconnectable with interconnectable paver blocks. The culvert structure comprises an elongated rigid casing having a bottom wall, opposed parallel vertical side walls, and an open top end. One of the vertical side walls has at least one projection formation for interconnection with a slot of adjacent ones of the paver blocks in a paved surface formed by the paver blocks. The other of the vertical side walls has a slot formation for interconnection with a blocks engaging projection of adjacent ones of the paver blocks in the paved surface. The bottom wall has passage means for the evacuation of water therethrough and a support structure connected to the rigid casing for supporting a grate over the open top end.

I claim: 
     
       1. In combination, a culvert structure interconnected with paver blocks, the paver blocks being interconnected to form a paved surface, said culvert structure comprising a rigid casing having a bottom wall, opposed parallel vertical side walls, and an open top end; one of said vertical side walls of said rigid casing having at least one projection formation interconnected with a slot of adjacent ones of said paver blocks, the other of said vertical side walls of said rigid casing having a slot formation interconnected with a block engaging projection of adjacent ones of said paver blocks, said bottom wall of said rigid casing having water evacuation passage therein for the evacuation of water therethrough and a support structure connected to said rigid casing for supporting a grate over said open top end. 
     
     
       2. The combination as claimed in  claim 1  wherein said projection formation is an elongated formation extending along said one of said vertical side wall and shaped for tight fit engagement in said slot of said adjacent paver blocks. 
     
     
       3. The combination as claimed in  claim 1  wherein said support structure comprises a pair of vertical support plates interconnected together and spaced apart by transverse interconnecting spacer plates, said vertical support plates resting on said bottom wall and having a top support edge extending a predetermined distance bellow a top edge of said opposed parallel vertical side walls and spaced inwardly therefrom to form a recessed support ledge for said grate. 
     
     
       4. The combination as claimed in  claim 3  wherein said vertical support plates are provided with vertical connecting slots for interengagement with said spacer plates. 
     
     
       5. The combination as claimed in  claim 4  wherein intermediate ones of said connecting slots are formed in said vertical support plates and disposed in transverse alignment with one another, and intermediate spacer plates for interengagement with said intermediate ones of said connecting slots. 
     
     
       6. The combination as claimed in  claim 1  wherein one of said vertical side walls is provided with a support ledge having a spacer plate engaging element interconnecting said spacer plates and intermediate spacer plates.
